Dos elementos son considerandos iguales si y sólo si
|
|
<literal>(string) $elem1 === (string) $elem2</literal>. Es decir:

cuando la representación de cadena es la misma.

Esta función sólo comprueba una dimensión de una matriz n-dimensional.
|
|
Por supuesto, se pueden comprobar dimensiones más profundas mediante
|
|
<literal>array_diff($array1[0], $array2[0]);</literal>.
